Add PCB drill and holder to 3d printer by Henry Wang

Açıklama

2021/5/14 Recently I add some functional accessories to my 3d printer. They have no interference with the normal 3d printer function. Now I add a PCB drill to it. It works very well. My 3d printer has become a multi-function CNC machine without interference from the 3d printer's normal use. I use a 20 degree, 0.2 mm v shape engrave bit for the test. It is very cheap compare to others. But it is already very nice for a newbie to do the test. For the PCB board, I also select a cheap one (not the one in the video, that is a very nice one). I have found the board has fluctuation even at the same surface. You can even see the defect spot even in the first-time use. This will decrease the quality of cutting preciseness. If possible please select a better one. The PCB board size is 100*70 mm. If you want to use a larger one, please change the design which I attached in the files. Happy modification. Have a nice day. https://youtu.be/cMkIkrN16lM | Download free and paid 3D printable STL files
